What is a Six-Speed Dual-Clutch Transmission?
2 Answers
Six-speed dual-clutch refers to a car equipped with a six-speed dual-clutch transmission, which consists of two transmissions. One controls the odd-numbered gears (1st, 3rd, 5th), while the other controls the even-numbered gears (2nd, 4th, 6th). While using the current gear, the next gear is already automatically prepared, resulting in extremely short shift times without the delay associated with manual transmissions. Here is more information about six-speed dual-clutch transmissions: Advantages: The six-speed dual-clutch transmission is based on manual transmission technology but falls under the category of automatic transmissions. In addition to offering the flexibility of manual transmissions and the comfort of automatic transmissions, it also provides uninterrupted power output. Working Principle: The six-speed dual-clutch transmission contains two sets of clutches and two input shafts. It achieves gear shifts through the coordinated operation of integrated electronic and hydraulic components.
As an auto mechanic, I disassemble transmissions every day. The most fascinating thing about the six-speed dual-clutch is that it has two sets of clutches! One manages gears 1, 3, and 5, while the other handles gears 2, 4, and 6. During gear shifts, the two clutches work like a relay race—one disengages while the other immediately engages, making shifts as fast as hitting a hotkey in a video game. The Volkswagen Golf GTI uses this system, and you won't even see the tachometer needle twitch while driving. But a heads-up: it comes in dry and wet types. The dry type can overheat in stop-and-go traffic, while the wet type, submerged in oil for better cooling, is more expensive. The dual-mass flywheel also significantly reduces vibration, making it much smoother than a regular manual transmission.
